To ull whom it 'may concern:

Be it known that I, Jol-YN t). tlmyorvicei.,

Jr., ot' Boston, in the Count-y ot' Suttolk and Stilte ol Massachusetts, have invented eertein new and useful Improvements" in 'lire- Protectors, oit' which the following' .is o speci.. tiention.

This invention relates to n protector or shield intended '.t'or use in monding the snoer.` for pneumatic tires, or oi,etrengtheningl weakened port of the tire shoe.

The invention is particularly designed 'for automobile tires in which an outer shoeincloses nn air-tight inner tube.

The object is to enable blow-outs or rini cuts in tire Shoes lto be repaired quickly, witlr out` necessity of vulennizntion, and also to reii'iforee u. weakened port oil the tire.

l accomplish my object. by providing :l protector or sleeve `which is designed to sur .round the injured or weakened port. oil the shoe. llt4 is provided with e nieinber adopted lo he inside oi" the Shoe, fitting the inner enwuture thereof, and n ineniloe.` oriented to titi lie outside ond tit.` the external. curvature or forniotion of the shoe, whereby the entire extent orf the injured `pari 'ot the shoe it; wrapped about and covered by the protee* i101'. y

` ln the zieeotni'mnying drawings, l have finiti-trailed the manner in which the invention to be carried `into ettect7 showing the preferredtorni o't deviee in whieh l' here embodied the principles of the invention.

Figure l represents a perspective View ol. the device ready to be implied to the tire. Fig. represente n partiel eeetion ol n wlnael nud tire, ehowing` my protecting device en plied thereto. -lligz repre.sentel :L `crees Section oi the Wheel rino ond tire with the protector npplied thereto,Showing;- the parte en nn enlnrged scale.

The suine reference characters indicate the ,leonie ports in all the figures. y

lite'tferringl to the drawings, @represents the rim of u wheel havingr the inturned flanges l) to engage the locking bende ot n tire shoe.

c' represente n tire shoe ot'4 any eonunon sort, eueh ne is known ns thev eleneher 'tire1 having bends (l which catch under the Menges of the rim when the tire applied thereto.

e represente the inner tube of oir-tight. uniterinl which ie eontoined Within the outer Shoe.

The commonest accidente to Vwhich 4the t outer shoes ol? tiren, particularly thoee used for motor vehicles, ore Subject, nre blow-oute or run outs, nud the device instituting my prennent invention ie deeigrued to repair both clashes ot' :u1-ridente, "lhie device eoneiete eefsentinlly ot n member f' curved longitudinnllj' und 'lrenxversely to lit accurately in the interior o'l the tire Shoe. und u rnemberlr/ similarly enz-red, buty of larger dimensions, to lit outside of the shoe. ll'ieee members nre connected by o flexible web l1. while un the unconnected edges ol' the members f und ,(7 nre tiene i und 7' reeiieetively.

li'elernlily the protector is Inode ol' the Saune sort; ot' nmteriul :is the shoes, to witj .liriotioned or rubber-iuuiregnnted "tuinie, with loyers ot rubber upon or between the loyers ot. lnbrie.

The nimmer 'in which the 'protector in used ie ns follows In ense '.L blow-out occurs nl; any port. ot: the shoe. the suine renloved from the rim, the inexnbeiLf oit the protector inserted in the shoe So ne to cover the broken place. theweb f1, tient about one of the bends ot the shoe. :ind the meniberg then nlured on the ouleide ol the shoe over the hole. the [iup y' ie then tuekei'l under the other edite of the shoe nud the flap 'z'` luid outside. ll'ie inner sho; ie then replzwed in the tire :inoitle ol' the member f and the entire shoe with the proteti-,tor und inner tube in platre ore ug'aiin put` on the wheel. lli/ben lthe inner tubo is intluted the preSsure thereof holds the internal nieniber oli the protector firmly and eolidl.v n oninet the inside o't' the Shoe, While the outer member 'of the protector is clasped about tho Shoe und held by the engagement. of the nebst/1 and with the tlnnigee ot the wheel riin. is 'the liep is placed inside ot the llofp Ai and entirely eorered und Surrounded by the lot:- tor, .find ne the lrietionnl qlmlilies of the me! teriol ore gri-ent., the outer member ot the protector is securely retained beyondl any possibility oi" the pneumntie pressure to distil-.Lee it.

Cit

bers of the protector, entirelysurrounds onel ed ot the tire shoe, While tlie'iips Y@and provide n double envelop for the opposite 1 edge of the shoe, The entire transverse portion of the tire affected is thus Wholly surrounded and enveiopedl by the members of the protector, and inside ns strong when new. ik

The only satisfactory ineens et present known of monding the blow-out is by Vuleanieing e patch into the tire. My protectcover performs thisv result in as effective i manner es Vulcanization, et e smellv frac-- this part of the tire shoe the tire, because 'vulcenizing is too toin for patching and My invention supplies this lack vby providnew ond uninjurel.
